Description
Sample vials 4 ml with screw thread are amber borosilicate glass 3.3 containers for laboratory sample storage, preparation and transfer. Each vial offers a nominal volume of 4 ml and dimensions of 45 × 15 mm, giving a practical mid-size format between micro vials and larger bottles. The screw-thread neck is specified for N-13 caps, supporting a tight closure that helps reduce leakage and evaporative loss during handling and short-term storage. Amber (brown) glass limits light transmission, which is useful when working with photosensitive solutions, standards or extracts, while borosilicate glass 3.3 provides the chemical and thermal resistance expected of quality laboratory glassware. Available as a pack of 100 pieces from manufacturer Witeg, these vials serve analytical chemistry, environmental laboratories and related workflows that need dependable screw-cap vessels at the 4 ml scale. Geometry suits standard racks and boxes used with N-13 systems. Select compatible N-13 closures for your application and observe normal safe glassware practice throughout use and cleaning.
This article is part of Sample vials & NMR tubes, in Tubes & vials.

Questions about Sample vials 4ml with screw thread
What is this article?
Sample vials 4ml with screw thread is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Sample vials & NMR tubes, inside Tubes & vials, in Labware.
A sample vial is a small closed bottle for keeping or for presenting a sample. An NMR tube is a precision glass tube: the wall has to be straight and the diameter has to match the probe, or the spectrum contains the tube.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
